Sorghum SbSTS1 was the first example of a stilbene synthase gene in monocots. Previously, we demonstrated that the gene was involved in defense responses. To examine its biochemical function in planta, SbSTS1 was overexpressed in transgenic Arabidopsis. Metabolite analysis revealed that
Sorghum SbSTS1, a pathogen inducible gene, was previously demonstrated to encode an enzyme with stilbene synthase activity. In this study, we attempt to identify the stilbene derivatives that accumulate in infected sorghum seedlings after inoculation with the anthracnose pathogen Colletotrichum
trans-Piceid and trans-resveratrol were authenticated for the first time by high-resoution mass spectrometry in red sorghum grains. A 0.4-1 mg/kg amount of trans-piceid and up to 0.2 mg/kg trans-resveratrol were quantified by reversed phase high-performance liquid chromatography-atmospheric pressure
